This is how the yucca grows at the ranch with no care whatsoever so no Ora I don't think my plant needs pruning. I did have a man trim the bottom leaves with a saw on a long pole so It isn't as dangerous and I trim the points off from time to time so the man who mows my yard doesn't poke his eye out. J. as for eating the leaves I have never heard of it but it could be. The hispanic people here in our county eat the prickly pear. They harvest it in the spring when the leaves are young and tender and no thorns yet. I think they cook it kind of like squash and some add it to scrambled eggs. I tasted it one time and didn't like it but I'm thinking it is something you have to aqquire a taste for and the hispanic population have grown up eating it so they like it very much. We were just given a jar of jelly made from either jalapeno pepper or chile petine (sp) not sure which. They told me to soften some cream cheese and add some of the jelly and mix and use for a dip. It is really good.
